It is not a good idea to put the Thread.sleep loop in the onCreate
method.
I recommend you use an AsyncTask to do what you are trying.
Something like this:
public class asyncphoto extends AsyncTask<Void, String,
Void> {
protected Void doInBackground(Void... unused) {
for (String photo : photo_list) {
publishProgress(photo);
SystemClock.sleep(3000);
}
return(null);
}
@Override
protected void onProgressUpdate(String... photo) {
bm = BitmapFactory.decodeFile(photo[0]);
ImageView01.setImageBitmap(bm);
ImageView01.setScaleType
(ImageView.ScaleType.FIT_XY);
}
protected void onPostExecute(Long result) {
Toast
.makeText(AMLTimerTask.this, "Done!",
Toast.LENGTH_SHORT)
.show();
}
}
Just fire up the async task within your onCreate method: new
asyncphoto().execute();
